News!!!!
I sent one of these to a lad in australia, he came back and said for his B-16 unit
it was wrong , so either I have made a mistake or there are two versions ( I know there are 3 Variants in the B-16)
I have enclosed a photo for the two Variants to clarify whats what, the larger one pinch wheel peg is pressed in and the arm has like teeth in to hold the spring, the smaller one is about half the size and the peg can be removed
Larger one is my stock number S832
Smaller one is my stock number S1205
Used in the B16 and now I have seen the E16
